With the water supply off and the system depressurized, use a pipe wrench or large adjustable wrench to disconnect the flexible water line from the top of the cold water inlet nipple. Once the line is disconnected, carefully use the wrench to unscrew the entire inlet nipple assembly from the threaded port on the top of the water heater tank. Remove it for inspection.
Goal: Locate and remove the source of the blockage
- The nipple may be seized. Proceed with caution to avoid damaging the threads on the water heater tank.

FAQs
What are the most critical safety steps I must take before beginning to replace my well pressure tank?
Absolutely always turn off the power to your well pump at the main electrical panel first. Then, fully drain the entire water system to relieve all pressure. This prevents electric shock, water damage, and injury from pressurized components.
How long should I expect this well pressure tank replacement to take, and what's the approximate material cost for a DIYer?
For a beginner, plan for 2-4 hours, assuming you have all tools and materials ready. The material cost, primarily for the new pressure tank and fittings, can range from $200 to $600, depending on the tank size and brand, plus a few dollars for tape and rags.
Why is correctly pre-charging the new well pressure tank so important, and what pressure should I set it to?
Pre-charging with air prevents the tank from becoming 'waterlogged' and ensures your pump cycles efficiently, extending its lifespan. Set the tank's air pressure (when empty) to 2 PSI below your well pump's 'cut-in' pressure (the pressure at which your pump turns on).
Which specialized tools are absolutely essential for replacing a well pressure tank, beyond basic household tools?
You'll definitely need a sturdy pipe wrench (like the 16-inch self-adjusting one mentioned) for plumbing connections, a tire pressure gauge to check the tank's pre-charge, and a water pressure gauge to monitor system pressure. Slip-joint pliers are also very helpful for various fittings.
